When attempting to play a 4K Ultra HD Blu-Ray movie using PowerDVD 18 Ultra I get an error message that says I need to install SGX PSW runtime and to click on Install. When I click on Install it says:
The installation was unsuccessful because this platform does not support SGX, or is disabled in BIOS.
AMD Ryzen 7 2700x
Gigabyte X470 AORUS Ultra Gaming mother board
Gigabyte GeForce GTX 1080
Pioneer PIO-BDR-211UBK BD/DVD/CD Supporting Ultra HD Blu-Ray Playback
From what I have read (so far) it seems that SGX is Intel platform specific. I have to believe there is a work around for AMD. If not this is a MAJOR issue.
